Hi, after 4 and a half years my bosch 069 has completely died just outside of warranty. Its been pretty useless since I bought it even with a battery cutoff.

I don't know if it makes a difference but the car is a japanese import.

At the time there was a more expensive 334 model but at the time I couldn't find any information of people fitting it in the 300zx. Now ive realised that it has a capacity of 830cca vs the 069 capacity of 630cca.

There appear to be 3 brands to choose from and I cant find a definitive answer on which brand to go with.

There is Yuasa https://www.eurocarparts.com/p/yuasa-battery-44477334Z,

Varta https://www.eurocarparts.com/p/varta-blue-334-car-battery-4-year-guarantee-444773342,

and Bosch https://www.eurocarparts.com/p/bosch-s4-car-battery-334-4-year-guarantee-444773347.

 

I don't know which one to select and have found some others mentioned on the forums and dont know what to go for

I dont know what to go for, as the other batteries i've found in previous threads don't come up as compatible and I don't want to end up getting the wrong battery. But I also don't want another smaller capacity one and my experience with the bosch 069 has put me off them a bit.

 

Do you drive your Z all year round or does in go into storage at Winter?

Gets driven once or twice a  month, and i put it on charge occasionally as well. 

Some info here.

Yeah that where i got the suggestions for the e44 https://www.tayna.co.uk/car-batteries/varta/e44/ and the e38 https://www.tayna.co.uk/car-batteries/varta/e38/ from. 

But it didn't confirm whether the e44 actually fit and was used.

Both also have smaller cca than the 334 model batteries from eurocarparts, which no one has used. But then i'm left with my original dilemma of choosing between Yuasa, Varta and Bosch aha

 

My battery used to die after 4 to 5 years of use  but I keep it garaged all Winter the charged it up for the Spring/Summer. Now I have a trickle charger on at Winter and so far the battery is still good. 

Unfortunately I don't have a garage so I cant keep it on a trickle charger, only a driveway.

As mentioned before, I have a battery cutoff to reduce battery drain as much as I can. But the battery is dead so it still needs replacing.

I don't mind having to replace it in another 5 years, I just want to pick the best one I can.

I bought a Yuasa 3000 series (part no 030) from Allparts back in March 2020 - only cost £107 - and have had no problems with it. 

I also keep a spare one (same model) on the garage floor next to the Zed, to serve as a booster - and so far it hasn't been needed.

Thanks, I ended up getting the E44
